This Cotoneaster, being a naturalised cultivar, has been determined by Jeanette Fryer from these images.
It is C.franchetii Bois Series FRANCHETIOIDES - which represents a NEW RECORD of an Alien plant for the vice-county of Buckinghamshire. According to 'Alien Plants of the British Isles (Clement & Foster, 1994) Franchet's Cotoneaster has been confused with C.dielsianus and C.sternianus. Established garden escape mainly in S.England and Ireland including on an open limestone rock-face near Killarney. A native of Yunnan. It has been common in cultivation since early 1900 in areas of Europe where the winters are not too cold (which applies to where I live) and on the west coast of North America. This shub is extremely attractive in autumn when weighed down with orange-red, pear-shaped fruit which contrast well with the silvery-gray foliage. It is wind tolerant and good for planting in coastal regions. Interestingly, I came across a different Cotoneaster, also naturalised, perhaps some 1.5km away, which proved to be C.sternianus Series STERNIANUS, which C.franchetii has been confused On Thursday, November 17, 2016 at 3:00:52 AM UTC, JM Garg wrote: > Thanks, Chadwell ji > ---------- Forwarded message ---------- > From: "C CHADWELL" <[email protected] <javascript:>> > Date: 17 Nov 2016 6:55 am > Subject: Photographing Cotoneasters when in fruit: how it should be done > To: "J.M.
